A Mexican fish that can repair its own heart offers clues for future treatments in humans, according to new research.
Scientists discovered a gene that may hold the key to the fish's ability to regenerate its heart tissue.
The same gene, called Irrc10, is present in humans, and researchers at Oxford University say their new findings hold potential to change the lives of heart attacks patients.
Over half a million people in the UK are living with heart failure, often as a result of a heart attack, according to the British Heart Foundation, who funded the research.
